10-pack 3×3″ Replacement Electrode Sponges – Bi-Monthly Subscription
These 3×3″ sponge inserts are used to replace the original sponges that come within our 3×3″ Amrex Sponge Electrodes. In addition, these sponges will serve as replacements for the one’s included in our Basic tDCS Kit.
Over time the sponges within sponge electrodes can grow brittle and crumble, crack, or split, causing an uneven distribution of current, and reducing the effectiveness of tDCS. Worn-out sponges can also results in uncomfortable tDCS sessions. The most common side effects reported with the use of old sponges are increased tingling, itching, and sometimes mild stinging sensations. Therefore, it’s a good idea to replace your sponges regularly to ensure your electrodes function properly for optimal tDCS sessions.
We believe it is best to replace tDCS electrode sponges every two weeks, or every 7 tDCS sessions. However, the best results can be obtained by using new sponges for every session.
